WATER-WHEEL.

nearer. 7

To all whom it may concern Be it known that I, THOMAS CRIsr, a c1t1- zen of the United States, residing at Jayton, in the county of Kent and State of Texas, have invented certain new and useful Improvements in Water-Wheels, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in water wheels and has relation more particularly to a device of this general character adapted to rotate about a vertical axis, and the object of the invention is to provide a device of this general character of a simple and comparatively inexpensive nature having means of a novel and improved character whereby the same may be causedto rotate by the flow of the water into which it may be inserted with a maximum of eliiciency. The invention consists in the details of tain important advantages are attained and the device is rendered. simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

' The novel features of the invention will be carefully defined in the appended claim.

. plied being in section; and Fig. 2 is a sectional view taken on the line AA of Fig. 1.

In the embodiment of my invention disclosed in the accompanying drawings, 1 denotes a vertically disposed shaft suitably mounted for axial movement and which is provided at its upper extremity with a gear 2 adapted to mesh with a second gear 3 aflixed to a shaft l whereby the power created by the rotation of such shaft 1 may be employed for any purpose required.

While I have shown the use of the gears 2 and 3, I do not wish to be understood as limiting myself in this particular respect as any means may be coupled with the shaft 1, as will operate with convenience and facility. Suitably afiixed to the shaft 1 and in spaced relation are the hubs 5 from which radiate the arms 6-6 which may be of any Specification of Letters Patent.

desired number but herein shown as four,

such arms of each of the hubs being in vertical alinement.

l/Vhile the connection of the hubs 5 is preferably such as to prevent movement thereof endwise of the shaft 1, I find it of particular advantage to tie or connect the alined arms 66 of the hubs 5 by the rods or braces a7 whereby it is assured that such arms will be maintained in their proper spaced relation.

Projecting from one of the side faces of each of the arms 6 of the upper hub and rearwardly thereof when compared with the direction-of flow of the water with which my improved water wheel is adapted to be employed, are the spaced longitudinally alined substantially annular members S 8 adapted to afford a means whereby a blade or wing 9 may be suspended, such blade or wing 9 being of a width substantially equal to the length of the arms 6 and of a height sufficient to overlap the inner marginal portions of the alined arms 6-6, whereby it will be readily perceived that the movement of such blade or wing in one direction is so obstruct ed or limited as to cause such arm;6 to move axially under the impact of the water during its flow. In order to afford the best connection between the blade or wing 9 and the an nular members 8, I provide such blade or wing in its upper marginal portion with the perforations 1010 through which the lower portion of such annular members extend, the curvature of such members 8 being such as to permit the blade or wing 9 to ride therearound without any resistance being offered to its swinging movement in one direction by the contact of the upper marginal portion of the blade with the adjacent face of the upper arm 6.

By the arrangement of the blades, hereinbefore set forth, it will be observed that a feathered efifect is created when the blades are moving in a direction opposite to the direction of the flow of the water and in order to assure an immediate response of the blades or adjustment thereof into an elevated position, it is to be observed that the forward upper marginal portion of the lower arms 6 are inclined forwardly and downwardly, as indicated at 11, whereby it will be readily perceived that the entering edge of each of the lower arms is substantially knife-like and that the direction of inclination will so act upon the water as to give an upward flow thereto adjacent the lower or free portion of the blade as to assure such blade assuming an elevated position substantially at the moment it passes the center of the direction of flow of the water. In contradistinction to the beveled upper face 11 of the lower arm 6, it is to be observed that the forward edge or face of the upper arm 6 is flat and vertically disposed. By this arrangement it will be perceived that an eddy is created in the water in advance of the pivotal points of such blade which will result in a greater impact or force upon such blade at a point below its pivotal connection and resulting in what might be termed a leverage action cooperating with the lower portion of such blade, which assures a better response of the blade at the time it should be adjusted into an elevated position.

I have also found that the operation of my improved water wheel is greatly enhanced if means are provided to prevent slip over or below the arms 6-6 and, as herein shown, I accomplish this purpose by securing to the outer faces of such arms 6 the disks 12-12, such disks being imperforate and extending from the shaft 1 to the outer extremities of such arms 6 and while these disks 1f212 may be of any preferred configuration, I find it best that they be circular in form.

While the particular mounting of my improved water wheel forms no essential part of my invention, it might be well to state that when the conditions so warrant it that such wheel may be mounted within a suitable boxing open at its opposite ends and through which the water may be caused to flow, such boxing being indicated in the drawings, as at 142.

From the foregoing description of my improvements, it is thought to be obvious that a water wheel constructed in accordance with my invention is of a simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be applied and of the minimum of resistance offered in its axial movement and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles anc spirit thereof and for this reason ll do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

A device of the character described including an axle, arms radiating from such axle, blades pivotally supported by certain of such arms and adapted to abut the re maindcr of the arms to limit their movement in one direction, and imperforate disks secured to the arms above and below the wings, the forward faces of the lowermost arms being inclined upwardly and rearwardly to afiord knife edges, the forward faces of the upper arms being vertically disposed.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
